What causes severe jerking during the Changan Eado's initial acceleration?

[LeAndrew]

If your Changan Eado experiences jerking sensations during acceleration, you can first check whether water has entered the transmission. If so, replacing the transmission fluid may resolve the issue. To address jerking sensations, it's also necessary to clean carbon deposits from the throttle body, inspect the fuel injectors for blockages, and examine the spark plugs. Below are some potential causes and solutions related to vehicle jerking: 1. Special circumstances: Check whether the ignition system has been exposed to water. Sensors or water ingress in the intake system may wet the air filter, affecting air intake volume and potentially introducing small amounts of water into the system. 2. Common causes: The transmission fluid passages may be obstructed or not flowing smoothly. Wear in the valve body, prolonged use of deteriorated transmission fluid leading to reduced lubrication effectiveness, or a dirty transmission filter with poor filtration allowing wear particles into the valve body can all contribute to jerking sensations.
